The cruise ship Ruby Princess docked at Pier 27 in San Francisco on Thursday for disinfection following an outbreak of norovirus that affected more than 120 passengers and crew members. The vessel was on a 20-day voyage when the illness, commonly known as the stomach bug, began to spread.

Princess Cruises, the operator of the Ruby Princess, stated that enhanced sanitation protocols were implemented across the ship. The company reported that the number of cases has decreased since these measures were put in place. Officials confirmed the ship is undergoing thorough cleaning and disinfection before its departure for its next scheduled voyage.

The Ruby Princess's stop in San Francisco is a routine procedure for such health incidents. The ship is equipped to handle medical situations onboard, but docking allows for a more extensive decontamination process to prevent further spread and ensure passenger safety.
